How to turn a Dodge airport tug into a trail slayer

Sometimes, having a ton of fun requires takes a ton of work. Just nine days before the so-called Ultimate Adventure 2014, the folks behind 4-Wheel & Off-Road had 40 tasks to complete in order to turn the ratty truck pictured above into a machine that could excel on treacherous off-road trails while still being able to handle highway jaunts. Much of process behind the build was chronicled on the latest episode of Dirt Every Day.
The team's vehicle started life as a 1990 Dodge tug truck that spent part of its life hauling around airplanes. The builders hung on to the Cummins six-cylinder diesel, but they tossed out practically everything else for the project, with some seriously heavy-duty replacement parts for the transmission, transfer case, axles and a whole lot more. The process was certainly a ton of work, but the end result looks like a fantastic crawler.
Sure, it might have been easier to bring a truck that was already prepared, but where would the fun in that have been? Stay tuned until the end of the video for a few glimpses of the completed Dodge and peek at some of the punishment it goes through.

Dodge Viper recall requires small-handed mechanics

It has been over a year since Chrysler first announced its recall of 3,660 2003-2004 Dodge Vipers because the airbag could suddenly deploy. The repairs are finally beginning, and it appears to be a nightmare for mechanics.
According to the automaker's filing with the National Highway Traffic Safety Administration, the airbag control module can fail, which causes the bag or the seatbelt pre-tensioner to deploy without warning. It took over a year to design the new parts, according to The New York Times. However, Chrysler finally has a new "jumper harness with an in-line diode filter circuit" ready to fix the problem.
The dilemma now moves to the mechanics who have to actually install the part. A 47-step guide from Chrysler explains that the procedure should take about two hours. It's not an easy job, though. Most of the dashboard has to be taken apart, and the instructions include this helpful bit of advice: "Installing the jumper harness and filter box into position is not an easy task. Patience, perseverance, and small hands are required." We wish the best of luck to them. The fix comes just in time for the Vipers to enjoy the summer sun.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
